LTR of 11months is hosting a "get together" for her co-workers ar her lake house this Friday. I'd be completely fine with it, but it's gonna be an overnight event. Which, to be honest is making me feel isnecure, I know there will be alcohol involved and I know that she has male coworkers that are in to her. No idea how to handle this situation, plus I'm not sure if her actions are sufficient enough to justify my jealousy or is it simply a red flag that should not be tolerated.

I need advice on how to navigate this situation.
